set the value of multiple fields in an existing struct

Hello,

I have an existing structure and I would like to update a couple of fields with some new values.

Is there a way to do this without using a for-loop?

% Original struct
OLD = struct('field1',1,'field2',2,'field3',5,'field5',9)

% Struct containing the updates
NEW = struct(           'field2',7,'field3',8)

% Update original with loop
fn_NEW = fieldnames(NEW)

for i = 1:numel(fn_NEW)
    OLD.(fn_NEW{i}) = NEW.(fn_NEW{i});
end
